Quite simple. I have studied sharks for 5 years. Im only ten. They dont have lungs. They have to keep moving to force water through their gills. Other sharks like the White Tip Reef Shark can suck it in. So they force it through their gills and the gills extract the water molecules and let the oxygen molecules that have evaporated in the water flow down to the heart. The heart pumps them through a network of veins to the body cells The body cells turn the nutrients into energy. When the body cells do this the make a waste gas called carbon dioxide (c02) The heart can pump two ways so it pumps up the c02 back to the gills that extract them back into the water. It has to do that each breath.
A shark's respiratory system consists of gills, which are located on the sides of the head and are responsible for extracting oxygen from water. The oxygen is then absorbed into the bloodstream through tiny capillaries in the gill filaments. Sharks also have spiracles, small openings behind the eyes that allow for passive water flow to the gills when the shark is resting on the ocean floor.
